Passed through Aden 3 times. First in Nov '62 when there were very few restrictions and little was out of bounds - wandered round Steamer Point shops and Maala (Maalla?) night clubs without problems as a callow youth. Secondly on finishing training in '64 when there were many more restrictions and armed guards with grenade nets round the Red Sea. I also think that the busses were protected by guards. Finally in 66 on leave when I managed to stay in the Mess at Khormaksar as down town was barely an option for transit. Great changes in a very short time!
